20130180663 | Tooling Systems and Methods for Composite Parts - A tooling system for forming a part comprises a sheet structure, a truss structure, and an attachment system. The sheet structure is a carbon fiber composite structure and defines a mold surface for defining at least a portion of the part. The truss structure comprises a plurality of truss components. The truss components are tubular and are made of Invar. At least one end of each of the truss components is crimped. Crimped ends of the truss components are welded to other truss components to form the truss structure. The attachment system secures the sheet structure to the truss structure. | 07-18-2013 |
